1. A method for monitoring the functioning of an RFID-based radio communication network in a spatially extensive area, wherein a plurality of RFID tags carry out a radio communication with a reader, comprising:

  • carrying out, in the area of coverage of the RFID system in which at least one fixed reference RFID tag is arranged, a periodic radio communication between the at least one fixed reference RFID tag and the reader;

    sending the data from the reader to a control center;

    comparing the data in the control center with previously transmitted data relating to the at least one reference RFID tag;

    arranging the reference RFID tag in a marker field of a marker device that generates a spatially delimited electromagnetic field in a specific geographically delimited area of the area of coverage of the RFID system, andwherein the data stored in the control center relating to the radio communication with the reference RFID tag is field strength data indicating a field strength of the received radio communication, and the field strength data for each communication is compared with previously received field strength data.
